The vest is worked using the domino knitting technique. The domino diamond construction means that the armholes are quite low.
The design is worked in two identical sections – a front and a back. The sections are sewn together at the shoulders as well as along the side seams. After this, half diamonds are worked to create the straight edges at the hem. At the end rib edges are worked along the neck edge, hem and armholes.
